v8.0
We increased the WT_MIN_STARTUP_VERSION to 11.2.0 in WT-10307 as part of the work to handle 8.0 upgrade and downgrade. This change has disabled direct upgrade from WiredTiger 4.4 data format to 8.0 data format (not through MongoDB).
From WiredTiger's point of view, we don't see the need of this restriction. The only data format change in 8.0 is to write the page deleted timestamp to disk. From our knowledge, MongoDB is still not using timestamped truncate in 8.0. Therefore, we believe there is no need to restrict WiredTiger's upgrade version at this point.
We need to chat with the server team to understand why we need to do this and agree on what should be the path forward.
